Types of Performance Tests | David Tzemach

Overview

In order to
achieve the best from your performance tests, you can combine few testing types
that available under the term of “Performance”, a good and effective
combination will lead to better and more precise results.

Please note,
that for this post I will list each type of test, with a very short description
(but I promise to create a dedicated article for each one of themJ).

Types of Performance
tests

Spike Tests

Testing the software with sudden overloads, the main goal is
validate that the software can handle situations where there is a sudden jump
in the user activity.

Reliability /Endurance / Soak Tests

Testing the system with different load for a long period of
time, the main goal is to see that the system can handle sustained use for a
long period of time.

Load Tests

Testing the software with increasing set of data (Near to
the software limitation), the main goal is to see that the software can handle
such loads without having any side effects (unexpected crushes, memory leaks,
bottlenecks Etc.).

Scalability Tests

Testing the software performance while increasing the volume
of users/environment and determine how the software will adjust to the growing
scale.

Stress Tests – testing
the software under load that exceed the system limitation, the main goal is to
cause system failures , analyze the
crash, and determine the way that the software recover in case of such failure.

Fail-Over/fault-tolerance
Tests

Testing that the software corresponding to failures while
involving two or more physical nodes, in this type of tests, we need to
validate that in case of failure the users can continue with their work and the
application data/services are moved to the available “Active” node.

Redundancy Tests

Testing the application redundancy mechanism in case of
load, the main goal is to determine the effectiveness of the balancing
system.

Volume Tests

Testing the application with different amount of data, the
main goal here is to understand the limits of our application and demonstrate
how a specific amount of data can affect the predefined requirements.
